Refrigerator-Cars and the like,of which the follmving is aspecification.

My invention relates to the heating of railway cars. particularly bysteam, and the 1 primary object of the invention 1s to provlde asuitable equipment for supplying'heat, as occasion may require, torailway cars such, for example, as refrigerator cars Which ordinarily donot require heating but which it is desirable to heat during certainperiods.

and in certain seasons When ce'rtainkinds of fre ght, such, for example,as fruit or vegetables are transported.

It is customaryto use refrigerator cars for the transportation of fruit,vegetables,

and like perishable commodities in certain seasons or in travel throughcertain" parts of the country WlilllOLIlT having suchcars iced. W hensuch commodities are subjected I in transit to comparatively 'loWtemperatures not only is icing unnecessary but it is desirable to heatthe cars in order to avoid the danger of freezing-although possibly onlyfor a part of the journey as, for eX- ample, When fruitis transportedfrom a tropical or semi-tropical climate to more northerly regions.However, this heating of refrigerator cars, desirable as 1t 1s undersome circumstances, has not ordinarily been done, in the first place,because of the cost involved in equipping such cars With the heatingsystems of the type customarily used on railroad cars, which is veryhigh considering the comparative infrequency of the, occasions demandingthe heating of cars of this sort, and, in the second place, because ofthe space which the heating coils of such systems occupy in the car, thepermanent.

installation of heatingcoils in the car decreasing the carrying capacityof the car Without serving any useful function during the larger part ofthe time during Which the car is in service. The employment of stoves inthis connection'is objectionable as stoves require frequent fueling andconstant attention and, moreover, are likely tosetfire to the train incase of accident.

My invention providesjavery satisfactory heating equipmentffor cars ofth s type cone sisting, first, of steam heating or radiatlng derneaththe same, and is adapted to convey steam from the locomotive boiler, orother common source of supply of steam common to the several cars of thetram, and deliver the same preferably inautomatically regulatedquantities to the heating element or elements When the same are 1noperative position, and, third, an air circulatory sys-' tem Within thecar, preferably also a permanent installation, with which the heatingelements cooperate to produce auniform or relatively uniformdistribution of" heat through the entire, car. The air circulatoryfeature of my invention is not perhaps absolutely essential but is,nevertheless, a highly desirable feature of the invention. lVith anequipment of this sort the cost of heating refrigerator cars, and thelike, is sufficiently reduced and the space in the car sacrificed tothis purpose is minimized to such an extent that it is entirelyfeasible, practical and economical to heat such cars Whenevertemperature conditions, and the character of the cargo may require it.For example, if a railWay'oWns a thousand refrigerator cars the chancesare that only a small proportion of these cars at any time Will be usedunder conditions making heating desirable. If it Were necessary to equipall of these cars with the ordinary heating systems the cost ofinstallation might be ceived, to say nothing of the diminution incarrying capacity resulting from having steam coils permanentlyinstalled in each of said cars. By utilizing my invention a railroadcompany can equip each of its refrigerator cars with a train pipe,regulating devices and such piping as may be necessary to supply theheaters With steam from. the train'pipe and. carry off the Waterofcondensation, and in addition to this equipment it may have on hand justenough of the removable radiating elements of my inventionordinarily acomparatively small 1111111 Wlll do-to meet the requirements for heating such cars at such times and forsuch periods as they may need to beheatech These heating elements, moreover, may be distributed atdifferent points'on' the road as the traflic demands.
